Cop killers get a lot of extra attention in law enforcement, and with good reason. However, on 'CSI: Crime Scene Investigation' (Thu., 9PM on CBS), there's at least the chance that the murderer didn't know the victim was a cop. They probably knew, but the possibility had to be considered.

The victim was incarcerated along with the suspected killer. According to the warden it was a matter of walking a group of the Aryan Brotherhood by a group of black men. Now why you would do this is completely beyond us, unless you want to stir up something.

Ray was suspicious of the warden as well. Why was a former cop even in general population, he asked? But having no official avenue right away in any direction but the gathered criminals, he turned his frustration on them.

"I want your DNA!" he shouted to the group. "I want to see your hands! I want to see your eyes! This man you killed was a cop. So there will be consequences! Prison will not protect you!"

You know it gets serious when the normally reserved Dr. Langston loses his cool.
